36C
D24
a/b cup
Average American female bra size is 34B. Average European female size is 34C!Seeing as most women are wearing the wrong size bra, normally because they are measured in the old fashioned way, most women are wearing bra with bigger band sizes than what they need and smaller cup size than ideal. Recent research and theory suggests that the average size for women is around 34DD (rather than 36B as some have claimed). This reply isn't much different to the one above but it's something interesting to note. The average is harder to determine as 8/10 women are wearing the wrong size. lol
34 b is the average bra size in the us 36 is the best looking size
The largest common bra size would be a double D. Most commonly that is as big as the average breasts are. They do however make much bigger bra sizes for some women.
You can know a woman's bra size by asking her. If you do not think it is appropriate to ask her for her bra size, then her bra size is probably none of your business.
Average bra size in the USA for adult females about 36 C. Note that this takes into account the phenomena that obesity increase both cup and band size. You also have to take into account all the women who have been "augmented" so the average for un-augmented women is probably somewhere between B and C.
I doNt know the average, but I am 16 and my bra size is 34B and my girlfriends is the same ( i an a bisexual)
34B
I think most women who wear a 34" (bust) bra are a B cup. However, I am a 34C and that is pretty normal, too.
Every girl is different! And at 16, many girls (women) are fully developed. So if a B-36 bra fits you, then it is a good size for you. Many mature women wear an A cup, and many wear a DD - that's the beauty of diversity!
